JULIUS C. GOODWIN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- HALFTO MARCUS H. DARROVV AND FREDERICK CHASE, OF PHILADEL- PHIA,PENNSYLVANIA.

GAS-HEATER.

SPECIFICATION forming part of Letters Patent No. 735,752, dated August11, 1903. Application filed May 8,1903. SerialNo. 15 ,143. (Nomodelfi Beit known that I, JULIUS C. GOODWIN, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inGas-Heaters, of which the following is a specification.

My invention relates to improvements in gas-heaters of the type shownand described in my prior application, filed July 16, 1902, Serial No.115,779, allowed March 31, 1903.

My present invention, while embodying the same general construction andarrangement as that shown in the application above referred to, alsoembodies numerous details of. construction whereby the radiatinghoodsmay be moved to and from the burners by a less complicated arrangementand by which a greater amount of heating-surface may be obtained to heatthe air as it passes through the casing.

The nature of my invention will be more fully understood by reference tothe accompanying drawings, forming part of this specification, and inwhich- Figure 1 represents a vertical section taken through the centerof the heater on a line 1 1 of Fig. 2. Fig. 2 is a horizontal sectiontaken on the line 2 2 of Fig. 1, and Fig. 3 is a similar section takenon the line 3 3 of Fig. 1.

Referring now to the reference-letters of the drawings, A represents acylindrical cas-, ing, which is preferably made in the form of twoshells at and a, between the Walls of which is a layer of asbestos,mineral wool, or other non-conducting material for the purpose ofretaining a large amount of heat within the inclosure.

The casing A is provided with a table B, located about midway betweenthe top and bottom of the casing and supported upon a ring of angle-ironb. This table is provided with a series of holes or apertures B, throughwhich the air may freely circulate in passing from a pipe or connectionA, located in the lower part thereof, to the discharge pipes orconnections A, which are arranged at the top of the casing. In additionto the openings B the table B is also provided with a number of openingsB below which are arranged a series of gas-burners '0. Each of theseburners is provided in the ordinary manner with a circular burner-head Cand a mixing-tube C which is supplied with the requisite amount of gasdelivered by a supply pipe 0 through a nozzle 0 provided with aregulating cook or valve'C", the end of the mixing-tube C adjacent tothe nozzle C being open, so that as the jet is projected into the tube aquantity of air will be induced and, mixing with the gas, will beconsumed at the burner-head C with an intensely-hot flame free fromsmoke or odor.

Each of the burners C is provided with a radiator in the form of a hoodD, the hoods being arranged in a circular series about a central pipe E,which pipe projects through the table B and is secured thereto by aflange e. The pipe E is provided at the top with a dome E and at thebottom with a discharge connection E, which passes through the easing toany suitable point of exit. The pipe E is provided with a collar E abovewhich is mounted a sleeve E encircling a series of apertures 7c, andprojecting out from the sleeve is a series of small connections ciwhichunite the hood to the sleeve and form communications for the escape ofthe products of combustion from the hoods into the pipe E. The pipe E isprovided at the top with an innercasing E, which acts as a bafl'le andcauses the products of combustion to pass upward through the dome Ebefore they descend and pass out through the connection E In order tofacilitate the lighting of the burners, Iprovide one of the radiators Dwith a lever F, which passes through a slot F in the side of the casingand which by being moved "laterally'will cause all of the radiators toturn with the sleeve E and in so doing expose the burner-head C for thepurpose of lighting the same or examining them from time to time asnecessity may require. In most cases it is preferable to separate theproducts of combustion from the air passing through and being heated inthe casing A. Sometimes, however, where rooms are properly ventilatedand where it is desired to utilize the hot gases in conjunction with theheated air passing from the casin g, I provide the dome Ewith a damperG, which normally closes an opening G, but which may be withdrawn forthe purpose of allowing the hot gases within the dome to in terminglewith the heated air by withdrawing the damper through the medium of alever G which passes through the casing and may be manipulated by ahandle G The operation of my device is as follows: To light the burners,the lever F is turned, moving the radiators D to one side, and afterthey are again moved back into their normal position the products ofcombustion will pass through the same, heating them to a hightemperature, and will continue through the connections e to the dome Eand thence downward through the pipe E to the discharge connection E allthe parts traversed by the products of combustion being highly heated.The air which it is desired to convey to compartments to be heated isadmitted through the opening A and passing through the openings in thetable 13 will be heated by contact with the radiators D, the dome 1 andother connecting parts, and will be carried off to any points desiredthrough the pipes A Having described my invention, what I claim, anddesire to secure by Letters Patent,

1. I11 a gas-heater comprising in combination, a plurality ofgas'burners, rad iatinghoods arranged above the same, and connected to acentral discharge-pipe, and means for moving the radiating-hoods to andfrom the burners, substantially as described.

2. A gas-heater comprising a circular series of burners,a circularseries of radiating-hoods mounted above the same, connected to anddischarging into a central discharge-pipe, and means for rotating theradiating-hoods to cause them to move to and from the burners,substantially as specified.

A gas-heater comprising a hollow support, a sleeve surrounding the same,a series of radiating-hoods connected to said sleeve and in opencommunication with the hollow support, a series of gas-burners adaptedto engage the open ends of the radiators, and means to cause theradiators to move from and to the burners, substantially as specified.

i. A gas-heater comprising a hollow support constituting a chimney, aradiator mounted above the same, a discharge -pipe, leading from thelower end of the support, a series of radiators sleeved about saidsupport, and in open communication therewith, burners adapted to engagethe lower open ends of the radiators, and means to cause the radiatorsto move from and to the burners,substantially as specified.
